Scientists from CSIR-NEIST Assam have developed chemical process that turns dirty coal into biomedical carbon quantum dots(CQDs) to help detect cancer cells. Carbon Quantum Dots(CQDs) are carbon-based nanomaterials whose size is less than 10 nm or nanometre.These carbon quantum dots (CQDs) were produced from cheap,abundant, low-quality and high sulphur coals. The CQDs emits a bluish… Continue reading Cancer cell detection ‘dots’ developed from coal in Assam
